I stuck it on my brother machine at work and only issue that showed up was brake pedal switch so changed that anyway
I'm looking as poss a throttle body fault next as i believe the idle control valve is built into this (fly-by-wire throttle), would anyone else do same or recommend something else to do first?
If i do change the throttle body does it need coding to the ecu or can it be swaped over with a spare one?
